Her salary 4 years ago would have been $30,000.

If 45,000 is 15,000 less than double her previous salary, we must first add 15,000 to 45,000 to find what double her salary was.

45,000+15,000=60,000.

Since this is twice her salary, we divide this by 2.

60,000/2= 30,000.

So, her salary 4 years ago would have been $30,000.

I hope this helps!

Answer:

This is a tough one, I already know that GD is congruent to FG, so in order to find GD, you use pythagorean theorem, which will be GD^2+15^2=17^2 or 17^2-15^2=GD^2, which is 64 and square root tht is 8. Next, given that CD=15 and CD is Congruent to BC, this meant that BG must be congruent to GD and therefore BG must equal 8

An arithmetic progression has first term 11 and Fourth term 32. Fine the sum of the first nine term
schepotkina [342]

Let the first term be a, 4th term be a_{4}, difference between terms be d, and sum of first nine terms be S_{9}.

a_{4} = a + 3d

32 = 11 + 3d

3d = 32 - 11

3d = 21

d = 7

S_{9} = \frac{9}{2} (2a + (9-1)d)

   = \frac{9}{2} (22+56)

   = 9(11+28)

   = 9(39)

   = 325

Sum of first nine terms is 351.
